Marty McGuire Digs Worms!

A funny, accessible chapter-book series about an irrepressible third grader. Marty McGuire's third-grade class has a special assignment: Save the Earth! Even more exciting, the best project wins a special award. Marty's pretty sure her classmates' ideas won't stand a chance against her plan to turn the garbage from the school cafeteria into fertilizer. All she needs is a little help from her teammate and best friend, Annie--and the worms in her grandma's garden. But it turns out that worms are awfully SLOW eaters. And when the critters escape, the whole class starts grumbling. Can Marty save the Earth without losing her friends?
